SINGLESOLE SHOE.

Application filed December 5, 1924. Serial No. 754,165.

g This invention relates to improvements in the construction of shoes,and proposes a oheapening and simplification in the manufacture of sucharticles.

One of the features of this invention is to provide a shoe constructionin which a single piece of leather is caused to serve both as insole andoutsole.

A further object of the invention is the provision of a soleconstruction for shoes, in which the counter leather is retained betweenthe two portions of a split sole.

Another object of the invention is the provision of a shoe in which theupper and sole may each be formed of a single piece of material and maybe joined by a single stitch passing around the welt in the preliminaryassembling of the shoe.

lVith these and other objects in view, as will appear hereafter we haveshown one form of execution of our improved shoe in the accompanyingdrawing, in which Figure 1 is a perspective view showing a partlyassembled shoe;

Fig. 2 is a crosssection through the toe portion of the shoe;

Fig. 3 shows a longitudinal section of the shoe, and

Figures 4 and 5 are similar sections with modified heels.

The sole 1 is composed of a single piece of leather which is splitaround the welt edge, and a portion of the upper surface removed toleave a shoulder as shown at 2. At the rear, the sole is split from theheel forward to the instep, thus forming the two portions 3 and 4. Theupper 5 in the example shown,

is composed of a single piece of material, either single ply or having areversed inner lining layer. It may be drawn over the last after havingbeen shaped into an appropriate form and joined at the rear by astitching 6. The counter portion 7 of the upper is turned under theupper section 3 of the sole and tacked in place as shown at 8, with apossible interposition of packing 9 to give the proper form to theinside of the shoe. At the front, the upper is turned outwardly as shownat 10 to conform to the reentrant angle of the shoulder 2. During thefirst operations of assembly, the upper may be held in this position bytacks or staples 11, although this is not necessary for the constructionof the shoe. After the upper has been positioned upon the shoulderformed in the sole, a narrow welting strip 13 is placed over the upper,and the whole stitched down as shown at 14. This single operation servesto hold the upper and sole'in their final relation.

The welting strip 13 is continued at each end beyond the ends of theout-turned flange 10 of the upper, as shown at 13", so that the endstitches 14 are relieved from strain.

The heel 16 may be of any appropriate design as shown in Figures 3, 4iand 5. In Fig. 3 is shown a heel construction in which the heel wedge 17is inserted between the two sections 3 and 4 of the sole, and theseveral elements are-tacked together as shown at 29. In Fig. 4;, we haveshown a Cuban heel, in which the two sections 3 and 4 of the sole havebeen connected together, and. the heel 16 inserted entirely below thelower section of the sole. In Fig. 5 we have shown a French heel, whichismounted entirely upon the upper section of the split sole, and thelower section 4 has been cut away-at the instep end of the heel 16. Byproper conformation of sole and upper, the heel block 16 of Fig. 3 maybe omitted and a baby-sole shoe produced.

In finishing the shoe, the trimming welt strip 2-1 is placed over theseam shown at 14, and is cemented in place and rolled down to form aknurled edge if desired.

To support the instep of the shoe, it is provided with a steel springmember 26 which is inserted at its forward end into a gash 28 formed inthe shank portion of the sole, and at its rear end is tacked as at 29 tothe heel portion of the sole. It is obvious that this spring willsupport the instep of the shoe and the foot of the wearer. To preventcontact of this spring with the stocking of the wearer, we prefer toinsert a cover pad 30 of soft leather, which may be fastened in place byadhesive in the usual manner.

It is obvious that minor changes may be made in the details ofconstruction and the arrangement of the parts without departing from thespirit of the invention as set forth in. the appended claims.

Having thus described the invention, what we claim as new and desire tosecure by Letters-Patent, is

.1. 'A shoe having a one-piece sole wit-h a split heel portion and achanneled portion alongthe toe and instep periphery, a onepiece upperhaving its lower edge divided by gashes at each side, the instep and toeportion of said upper being outurned and seated on said channeledportion of said sole, the heel or counter portion of said upper beingsplit heel portion, an upper outwardly lasted at the front and inwardlylasted atthe counter between the portions of the split sole, a \veltingstrip located over the outwardly lasted portion of the upper andextending at each end beyond such outwardly lasted portion, and astitching uniting said sole, upper and welting and joining the extendedends of the welting strip directly to said sole, whereby to strengthenthe attachment of the upper to said sole at the line of junction of 2bthe inwardly and outwardly lasted portions of the upper.

In testimony whereof, we aflix our signa tures WILLIAM C. RE. BERNARDORASO.
